What to Look for in a USB Flash Drive

What is a USB flash drive? What specifications do you need to out look for when buying one? A flash drive is a plug and play, portable storage device or portable data storage plugged to the PC for the retrieval and storage of electronic data. The function is rather similar to the old office supplies like the floppy disk or CD ROM, only the flash drive is smaller physically and capable of storing several gigabytes of data.
Physically, a USB flash drive involves a miniature circuit board implanted with the sophisticated circuit essentials to work with the computer's operating system. The device is integrated with a USB (Universal Serial Bus) interface compliant to the computer port. As a computer peripheral device, a flash drive is small (less than 30g in weight); typically removable and data can be deleted or rewritten over with new data.
The selection of a USB flash drive compatible to the computer operating system is primarily influenced by capacity in gigabytes, along with other features that provide convenience in the transfer of information such as stored data security protection, physical size and the longevity of stored data particularly when device is unplugged from the computer for an indefinite period of time.
Capacity in Gigabytes. Due to the absence of moving parts, more storage capacity is available as compared to floppy disks that have been phased out since 2005. USB devices are available with capacities ranging from about 65GB to over 200GB, in corresponding range of prices with cost tied up to capacity in gigabytes.Information Security Protection. Password protection is a feature added to some USB drive models and integrated with drivers to expand compatibility even with older systems. What makes a USB flash drive different from other portable data storage devices is that the user need not reboot once the device is attached to the computer port - and no external power is needed as well.Convenience in the Transfer of Stored Data. Data files from a PC or laptop are retrieved, rewritten and stored in the USB drive. Transfer to another computer is done by simply plugging the USB drive pulled out from the previous PC and data can be accessed or stored automaticallyPhysical Size. Most flash drives available in the market are really so small. These are typically electrically insulated and encased inside plastic, metal or even rubberized casing that it can be carried along in a pocket or secured by a key chain. Moreover, the USB connector comes with a removable cap that is designed to retract into the body as a form of protection, although damage could not likely happen even if left bare.
USB flash drives are now necessary peripherals that must form part of the workplace office supplies. Remember, to look for the features that can enhance storage capability when looking for portable data storage for the computer.
